通过同步内触发惯性-视觉复合传感器，实现对远距离、高速动态目标的测量。将高精度惯性传感单元ADIS16355与普通单目摄像机同步触发采集，通过任意位置变化、光轴角度旋转，达到双目视觉效果，有效解决了三维空间运动目标定位问题。由激光按键控制图像起始帧的标注，同时产生高电平信号，与摄像机视频信号分离出的奇/偶场同步脉冲信号一起通过与门电路输出，作为单片机标记惯性数据的中断信号，实现同步测量，可有效消除错帧、丢帧等现象，精度可达微秒级，为惯性传感器与普通单目摄像机同步采集提供了一种有效的解决方案。

The long distance, high speed dynamic target measurement was realized by using the synchronous inner triggering inertial-visual compound sensor. Synchronously trigger the high precision inertial sensor ADIS16355 and ordinary monocular camera, monocular camera can achieve binocular vision by changing position, rotating optical axis angle. It can effectively solve the location problem of the three dimensional space moving target. Laser keyboard is used to mark image initial frame, at the same time high signal is produced, then the signal and the odd/even field synchronous pulse signal separated from the camera video signal are outputted through the AND gate, the output is used to realize synchronous measurement as the interrupt signal. It can eliminate frame stagger or frame lost, the precision can reach microsecond. It provides a general solution for synchronous acquisition of inertial sensor and ordinary monocular camera.
